Motion-Based Authentication in VR Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User authentication in virtual reality and augmented reality environments is challenging due to the inability to use traditional methods like keyboards and mice, leading to error-prone voice or gesture authentication and password-related issues such as forgotten passwords and security concerns.
Innovation Solution
A method and system that utilize motion analysis to authenticate users by prompting them to perform specific motions, which are detected by sensors and compared to stored biometric data to grant access to computer resources, eliminating the need for keyboards and mice.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional authentication methods (keyboard, mouse) are used in VR/AR environments, then authentication can be performed using familiar interfaces, but users cannot type on keyboards when wearing headsets and lack access to traditional input devices
Solution Approach 1:
The patent replaces mechanical input devices (keyboard, mouse) with motion capture technology that detects user movements through sensors. The system captures spatial coordinates of body parts over time and converts them into authentication data, eliminating the need for physical input devices in VR/AR environments.
Solution Approach 2:
The patent introduces motion capture sensors and coordinate processing systems as intermediaries between the user and the authentication system. These intermediaries translate physical movements into digital authentication signals, enabling authentication without direct interaction with traditional input devices.
2Adaptability or versatility
If voice or gesture authentication is used in VR/AR environments, then authentication can be performed without keyboards or mice, but the methods become error-prone and less secure
Solution Approach 1:
The patent replaces error-prone voice and gesture recognition with precise motion capture technology that tracks spatial coordinates of body parts. This substitution provides more reliable and accurate authentication data by capturing detailed movement patterns in three-dimensional space rather than relying on interpretation of voice commands or simple gestures.
Solution Approach 2:
The patent changes the parameters used for authentication from voice characteristics or gesture types to precise spatial coordinates and temporal motion patterns. By measuring position, velocity, and acceleration of body parts over time, the system creates more distinctive and reliable authentication parameters that are difficult to replicate.
3Ease of operation
If passwords are used for authentication, then users can access computer resources, but users experience forgotten passwords and security concerns
Solution Approach 1:
The patent replaces password-based authentication with motion-based biometric authentication. Instead of requiring users to remember and type passwords, the system captures and analyzes unique movement patterns of body parts, providing both convenience and enhanced security through physiological characteristics.
Solution Approach 2:
The patent enables the authentication system to automatically capture and verify user identity through motion patterns without requiring manual password entry. The system self-services the authentication process by comparing captured motion data against stored biometric profiles, eliminating the need for users to manage passwords.
Data Source
AI summary
A method for authenticating a user is presented. Responsive to a request for access to a computer resource, a computer system prompts the user making the request to access the computer resource to perform a new motion in an environment in which the user is monitored by a sensor system. Detected biometric data in the new motion performed by the user is identified by the computer system. A determination is made as to whether the user performing the new motion is an authenticated user based on comparing the detected biometric data with stored biometric data for a prior motion performed by the authenticated user. The computer system provides access to the computer resource when the user is identified as the authenticated user.
